C8051F826-GS

Overview

The C8051F826-GS is a mixed-signal ISP Flash microcontroller from the Silicon Labs C8051F8xx family, featuring a high-speed pipelined 8051 core operating at up to 25 MHz. It integrates 8 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. The device includes a 10-bit ADC with up to 500 ksps throughput, a capacitive sense module, and multiple digital peripherals including UART, SMBus, SPI, three 16-bit timers, and a PCA. It operates on a supply voltage of 1.8 V to 3.6 V within an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• High-speed 8051 core with pipelined architecture for efficient instruction execution
• Integrated capacitive sense module supporting buttons, sliders, and proximity sensing
• On-chip debug circuitry enabling non-intrusive in-system debugging without external emulators
• Flexible clock sources including a precise internal oscillator and external options

Applications

• Capacitive touch interface implementations
• Industrial control systems requiring mixed-signal processing
• Portable battery-powered instrumentation
• Sensor signal conditioning and acquisition

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for current lifecycle status as this family may be designated not recommended for new designs. Ensure ESD handling protocols are followed during storage and assembly.

Selection Notes

Select this part when a cost-effective 8051 solution with integrated analog capabilities is required. Consider the 8 kB Flash limit for application code size. Evaluate the 16-pin SOIC package constraints against available PCB space. Verify that the 1.8 V to 3.6 V supply range aligns with the system power design.

Part Context

This component belongs to the C8051F80x-83x series of mixed-signal microcontrollers. These devices are designed for applications needing both digital control and analog signal processing on a single chip. The series shares a common architecture but varies in memory size and peripheral count.

Replacement Considerations

Consult the official product selection guide for pin-compatible alternatives within the same family. Verify memory capacity and peripheral availability in potential substitutes. Note that newer generations may offer enhanced features or different packaging options.
